Abstract

The optical storage medium (1) comprises a read-only region with a substrate layer (2), an information layer (3), and a mask layer (4) with a phase change material for providing a super resolution near field effect, which layers are arranged as a stack of layers, and a re-writable region comprising a layer with a tracking structure for providing a tracking information. The tracking structure is covered by the mask layer (4) for using the mask layer as the information layer of the re-writable region. The optical storage medium is in particular an optical disc and the re-writable region a reserved area and/or an inner area of the optical disc. The apparatus for recording and/or reading data from the optical disc comprises a pickup unit providing a laser beam for reading data from the read-only region with the super resolution near-field layer of the optical storage medium, and uses this laser beam for recording and/or reading data on the information layer of the re-writable region. The pickup unit comprises in particular a Blu-ray disc type pickup in accordance with the Blu-ray disc system.
